Abstract: External cervical resorption is a special type of external root resorption that begins with the cervical of teeth, which is a pathologic phenomenon with a characterization of the hard tissue destruction due to the abnormal activities of odontoclasts. External cervical resorption is a complex and dynamic process that initially involves only periodontal ligaments, cementum, and dentin. In more advanced cases, the resorption lesion can affect the pulp tissue. Early lesions tend to appear latent, therefore they may be overlooked and not detected until symptoms appear at an advanced stage. This paper reviews the diagnosis and biological mechanism of external cervical resorption, and aims to provide a reference for the prevention and early blocking treatment of external cervical resorption.

Key words: external cervical resorption, diagnosis, odontoclast, biological mechanism
